First, the bearing selection stage, a number of factors need to be considered (for example: load, hardness, operating environment, etc.), first make good bearing design bearing has reached its maximum lifetime value (refer to "bearing design factors to be considered.")

Second, the correct storage, bearing before installing the best should be kept in their original packaging. We need to stay in a clean, moisture free, relatively constant temperature environment. Rolling should stay away from dust, water and corrosive chemicals. Shake and vibration may never destroy the mechanical properties of the bearing, so the processing and storage process should avoid vibration.
The general level of the bearing should save, after some heavy bearing long upright, will be deformed due to its own weight!
Also, coated with grease (or sealed) bearing be extremely careful, because oil after prolonged storage density change. When the bearing for the first time, there will be a certain degree of rotation noise. Therefore, in principle, these bearings should hold time FIFO to control!

Third, clean, which is very important for rolling bearings. Rotating ring of the bearing surface is very smooth, very sensitive to damage caused by pollutants. Particulate impurities will be subject to excessive rolling and rolling element bearings produce local pressure will eventually lead to permanent material fatigue.

Fourth, the comprehensive equipment before installation, bearing should carefully using a suitable tool installation and removal should choose the right tools! Industry experts have estimated that premature bearing failure, 16% were due to improper installation caused. Generally speaking large installations, usually take suitable bearing installation.
But in the maintenance or replacement work, diverse environment! I suggest that you, related drawings, maintenance manuals, product brochures need a closer look. Bearing elements should also be kept absolutely clean!

Fifth, careful installation and removal, has repeatedly talked about the previous installation of bearings (everyone if similar problems, here are some articles bearing installation), again briefly summarize:
1. Do not apply mounting force on the rolling element, which can easily lead to local rolling element and raceway contact surfaces of overload, resulting in premature failure of the bearings attain.
2, do not use any hard tools (such as hammers, screwdrivers, etc., I have seen too much with these two tools "hard" installed too strong) direct knock on the bearing surface, which causes the bearing ring fracture or break.
3, the general bearing not removed from the device, only the larger bearings will be removed due to preventive maintenance. Demolition process, first with the right tools, to ensure that no damage to the adjacent parts!

Six, proper proper lubrication, the lubricant can isolate the bearing surface, so as to reduce friction, to protect the metal parts and to prevent contamination and impurities. There are various greases for different operating conditions selected.
